a "cation" pronounced Cat Ion.
A negative charge is the opposite of an ion. An Ion with a negative charge becomes an Anion. Normally with a negative charge they are called Electrons. See electrons for more help
A charge which is not a positive charge is a negative charge.
An electron has a negative charge. Also an ion in which there are more electrons than protons has a negative charge. Such an ion is called as anion.
An ion is an atom with a positive or negative charge.
Yes, there is a limit to negative charge that can occur on an ion.
negative one
The charge for the bicarbonate ion (HCO3-) is -1.
Negative, when the ion gains an electron. When an ion loses an electron it becomes positive.
The hydroxide ion, OH-, has a negative charge of 1-.
If the ion is positive, then the loss of an electron will result in the ion having one greater positive charge. (A +3 ion will be +4.) If the ion is negative, then the loss of an electron will result in the ion being one less negative than it was previously. (A -4 ion wil be -3. A -1 ion will be neutral and have a zero charge.)
An ion does have a charge. That is what makes it an ion.
An ion's charge will be either positive or negative, but not both. The charges are mutually exclusive. A positive ion is called a cation, and a negative ion is called an anion.
